Canada, assignor to The Coffield Washer Com pany Limited, Hamiltcn, Qntario, Canada Application September 15, 1933, Serial No. 689,502 8 Claims. (01. as-s2) The invention relates to a safety shutter or guard attachment for clothes wringers, as described in the present specification and illustrated in the accompanying drawings which form a part of the same.

'Iheinvention consists essentially of the novel features of construction pointed out broadly and specifically in the claims for novelty following a description containing an explanation in detail of an acceptable form of the invention.

The objects of the invention are to avoid accidents which ordinarily occur in the operation of clothes wringers, where no safety attachment is applied due to the entanglement oi the users wearing apparel or hair of the head, orhands coming into engagement with the rollers and thereby causing considerable harm; to facilitate the operators work in wringing the clothing by providing a safety shutter which will act as a 1 guide for the clothing both in entering the wringer and leaving it as well as devising a means whereby the water from the rinsed clothing will be drained to its respective tub as desired; to furnish a safety shutter attachment which may be either auto- I matic or manual, that can be easily attached to any form of clothes wringer and of simple and durable construction, comparatively few parts; and generally to provide an attachment for clothes wringers which will act as a dual purpose Iin that it will guard the attendant from danger in personal contact with the rollers of the wringer and at the same time form a guide for the clothes into the wringer as well as a means for leading out the direction of the clothing from the wringers on the opposite side.

In the drawings, Figure 1 is a front elevation of a wringer showing the attachment secured thereto.

Figure 2 is an end elevation of the wringer taken in the direction of arrow A in Figure 1.

Figure 3 is a vertical sectional view of the wringer and attachment taken on the lines 33 in Figure l.

Figure 4 is a front elevational view of the attachment.

Figure 5 is an end view of the attachment.

Figure 6 is a fragmentary front elevational View of the rolls showing the eccentric and the trip in position on the roll shafts.

Figure '7 is an end view of Figure 6 showing the eccentric and the trip in operation.

Figure 8 isan enlarged end elevation showing means for supporting the end plates bythe spring attachment.

Figure 9 is an end elevational view of the rolls and operating parts aboutto tripthe attachment.

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings, there are two attachments as indicated by the numerals 13 and 14 which are secured to the clothes wringer on opposite sides and on each of the attachments are formed a pair of end plates 15 and 16 which are connected together by means of the upper and lower shutters 1'7 and 18 and the lower portion of the end plates 15 and 16 are secured by means of the pins 19 and 20 to the flanges 21 and 22 of the tilting drain board 23 which is situated beneath the rolls 24 and 25 of the wringer 26.

The roll shafts 2'7 and 28 of the rolls 24 and 25 have an eccentric 29 and a trip mechanism 30, the trip mechanism being on the lower shaft while the eccentric is on the upper shaft, and the trip mechanismis adapted to engage with the dog 31 which is mounted to one of the end plates and is for the purpose of tilting the tilting drain board for changing the position of the shutters of one attachment from a feeding device to a scraping and stripping device, and simultaneously changing the direction of flow for the water on the drain board.

In the operation of the wringer, it is used the very same as other wringers, that is to say, the clothes are fed in one side of the rolls and discharged at the other side, the only difference being that the hazard of the clothes becoming wrapped around the rolls or the operators hands being caught therein is completely removed, rendering the wringer practically fool proof.

Aswill be seen on Figure 3, the clothes are being fed from the left side and discharged from the right side. When in this position it will be noted that the upper and lower fins of the safety shutter on the feed side are out of engagement with the rolls while the fins on the right or discharge side are performing their scraping action, thus preventing any chance of the clothes becoming Wrapped around the upper or lower rolls.

The water shutter at the bottom and the drain board takes care of the wwte water. It will be seen on Figures '7 and 9, the position of the safety shutter is governed by the direction in which the rolls are rotating. This is accomplished by means of the dog 31 which is pivotally mounted on one end of the safety shutter and the double ended cam or trip lever which is rigidlymounted on one end of the roll shaft 28.

It will be noted on Figure 7 when the roller is rotated in the direction of the arrow, theposition of the safety shutter will remain unchanged because the double ended trip cannot engage the dog while travelling in the direction indicated. However, when the-roll is rotated in the opposite di-' rection as in Figure 9, the trip will engage the dogand trip the shutter'as shown, upwardly forcing the finsof the shutter into their scraping position. i

The eccentric 29 which is mounted on the upper roll shaft provides means for a feeding action upon the clothes. That is to say, it provides a back and forth motion to the upper fin of the safety shutter, thereby aiding the clothes in passing through the rollers. The inner edge of the ends of the safety shutter is in engagement with this eccentric and being pivotally held in posi-- tion, must necessarily stay in engagement and follow its course in rotation, thus providing the feeding motion to the upper fin.

The springs 38 and 39 are inserted and held at each end within the tube 40 which is pivoted to the end plates 15 and 16 by means of the pins 41 and 42 slidable in the slots 43 and 44 in order to permit the expansion or contraction of the attachments and provide the pressure required to keep the shutters against the rollers. Theend plates 15 and 16 have the set screws 45 and 45 for adjustment of the end plates so as to tighten or loosen the shutter against the rollers.

There are many various ways and arrangements whereby the tripping action can be accomplished without departing in any way from the essential features of this invention, and the applicant does not desire to confine himself in any wa to the acceptable form as shown.

There are other ways also in which guards or shutters could be attached to a wringer to provide v, damage to the clothes being wrung, heretofore unknown.

Another important feature in this construction is in the way in which the clothing can be automatically fed between the rollers by means of the guide p'ate which also acts as a guard so that there is no necessity, as occurs in ordinary wringers, to guide the clothing between the rollers with the operators hands thereby eliminating to a very great extent accidents that are caused thereby.

The attachments as heretofore mentioned may be applied to any form of clothes wringer and although operated through the movements of the rollers which in turn are operated by its own mechanism yet the attachments are independent with the actual operations of the wringer such as in the tripping mechanism for releasing the pressure of the rollers.

What I claim is:

1. In a safety shutter or guard attachment for clothes wringers, a plurality of rollers and means for operating said rollers, a drain board tiltedly secured beneath the rollers, safety shutters mounted on said wringer on either side of the rollers having fins adapted to form guides for the clothing as well as guards.
